But there are problems in existing wheel crane lifting reel process, the operating process of wheel crane handling reel is cumbersome on the one hand, when particularly carrying out service work in the factory building of limitation in height is arranged, operation is difficulty especially, to hang recondition expense also very high for rental car on the other hand, additionally increased the cost of overhaul.
The utility model content
The purpose of this utility model is to provide a kind of hoist roller maintenance jack up unit, to solve the technical matters of available technology adopting wheel crane lifting reel operating difficulties.
For achieving the above object, the technical scheme of hoist roller maintenance jack up unit provided by the utility model is: hoist roller maintenance jack up unit, comprise base and the carriage that is used for the jacking reel that is positioned at the base top, carriage be provided with for the bracket structure of the support end top force fit of reel, support the lift drive mechanism that is provided with for the driven bracket lifting between base and carriage.
Described lift drive mechanism is that corresponding matching is used two sleeve screw rod nut bodies with the driven bracket lifting, every sleeve screw rod nut body includes by bearing arrangement and rotates the support screw that is assemblied on described base and the drive nut that assembles with the support screw worm drive, and drive nut is wholely set with carriage or captives joint.
Described base is folding structure, and base comprises interlude and two folded section that are hinged on the interlude two ends, and two support screws of described two sleeve screw rod nut bodies are assemblied in respectively on two folded section, and the length of the interlude of base is not less than the length of support screw.
At the bottom of described bracket structure has deep-slotted chip breaker.
The top of described support screw is provided with the jack that rotates to drive support screw for inserting crowbar.
Usefulness of the present utility model is: when hoist roller maintenance provided by the utility model is used, make the support end top force fit of the bracket structure of carriage and reel, then hoisted by the lift drive mechanism driven bracket and hoist with the jacking reel, after reel hoisted, the maintainer just can carry out Maintenance and Repair to backup bearing and the bearing of the corresponding end of reel.And be provided with the bracket structure on the carriage of jack up unit, can play like this positioning action to reel when the jacking reel, prevent that rocking from appearring in reel in lifting process.Jack up unit integral structure provided by the utility model is simple, by the lifting of lift drive mechanism driven bracket, and then can drive easily the reel lifting, hoists simple to operate, and is easy to use.
Description of drawings
Fig. 1 is the structural representation (in figure, dotted line is reel) of a kind of embodiment of hoist roller maintenance jack up unit provided by the utility model;
Fig. 2 is the structural representation of carriage in Fig. 1;
Fig. 3 is the schematic diagram after the base of folding structure shown in Fig. 1 folds.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of embodiment of hoist roller maintenance jack up unit, jack up unit in this embodiment comprises the base 4 that extends transversely and the carriage 2 that is used for jacking reel 7 that extends transversely, carriage 2 be provided with for the bracket structure 6 of the support end corresponding top force fit of reel 7, at the bottom of this bracket structure 6 has deep-slotted chip breaker.Support the lift drive mechanism that is provided with for the driven bracket lifting between base and carriage, lift drive mechanism herein is that corresponding matching is used two leading screw and nut mechanisms with the driven bracket lifting, every sleeve screw rod nut body includes the drive nut 8 that is assemblied in the support screw 3 on base and assembles with support screw 3 worm drive by bearing arrangement, drive nut 8 is wholely set on carriage 2, two support screws 3 of two leading screw and nut mechanisms are along the bearing of trend layout of base 4, and two drive nuts 8 are arranged along the bearing of trend of carriage 2.
In the present embodiment, support screw 3 rotates and is assemblied on base 4, rotates for ease of driving support screw, is provided with at the top of support screw 3 for the jack 1 that inserts crowbar.During use, insert crowbar so that drive the support screw rotation.
In the present embodiment, base 4 is folding structure, and two folded section 42, two support screws 3 that base 4 comprises interlude 41 and is hinged on interlude two ends are assemblied in respectively on two folded section 42.Simultaneously, for the normal rotation that guarantees two folded section 42 is holded up, the length of the interlude 41 of base 4 is not less than the length of support screw 3.Herein, base is folding structure, is convenient for carrying like this, is convenient to carry out aloft work.
